QDR II SRAM — 72 Mbit at 250 MHz
The Infineon CY7C1513KV18-250BZXI is a 72 Mbit Quad Data Rate (QDR) II synchronous SRAM organized as 4M x 18 bits. It clocks at 250 MHz, delivering back-to-back read and write operations on every rising and falling edge of the clock — effectively doubling the data throughput per pin compared to a single-data-rate SRAM at the same frequency.
The 165-LBGA supplier device package (13x15 mm) requires a multi-layer PCB for signal fan-out and decoupling; the core supply rail at 1.7-1.9 V needs local bypass caps within 5 mm of the BGA balls to keep supply noise under 50 mV peak-to-peak at 250 MHz.
Infineon lists the CY7C1513KV18-250BZXI as Active (current production). The base product number CY7C1513 covers the full family of 72 Mbit QDR II SRAMs with varying speed grades and temperature ranges. The -250BZXI suffix denotes the 250 MHz speed grade, industrial temperature, and 165-FBGA package in tray format.
